Phys.org / Hydrogen shell detected around Nova Persei 1901 may be a planetary nebula

Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...

Medical Xpress / Air-sampling tunnel reveals major person-to-person differences in release of infectious virus

A study published in the journal Cell provides the clearest evidence to date that people infected with influenza actively expel infectious virus into the air and that the amount released varies enormously between individuals.

Phys.org / Agricultural soils exposed to controversial weedkiller may be unexpected breeding ground for hospital 'superbugs'

Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...

Tech Xplore / LLMs and creativity: AI responses show less variety than human ones

Can using a large language model (LLM) make a person more creative? Prior work has shown that using LLMs can make creative outputs more homogeneous, but this homogenization could stem from the specific LLM used or from widespread ...

Phys.org / A complicated future for a methane-cleansing molecule

Methane is a powerful greenhouse gas that is second only to carbon dioxide in driving up global temperatures. But it doesn't linger in the atmosphere for long thanks to molecules called hydroxyl radicals, which are known ...

Phys.org / A much more sensitive fentanyl detection strip, thanks to physics

Following the beginning of the COVID-19 outbreak, lateral flow assays (LFAs)—the category of test strips in which the presence or lack of a pink line indicates whether a specific molecule, like a drug or a virus, has been ...

Phys.org / The truth of timekeeping lies within: Key developments in understanding circadian rhythms

Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other environmental changes. This clock is a highly sophisticated yet simple timekeeping mechanism that is critically ...

Phys.org / Altered colony chemistry reveals a process that destroys termite societies

Several insect species, including ants, honeybees and termites, live in highly organized societies, also known as social insect colonies. Insects living in these colonies can take on different roles, such as reproducing, ...
